In a 2005 review, Timothy May wrote that some of Weatherford's thesis was "without question, controversial". Nevertheless, Weatherford "presents his case very eloquently and with an abundance of evidence demonstrating not only the indirect influence of the Mongols in Europe but also the transformation of the Mongols from agents of innovation in the Renaissance into agents of destruction in the European mind during Enlightenment." He notes that the book lacks footnotes, and notations in the back are hard to follow and lacking in many cases. In addition, he writes, "While the overall thrust of the book is on target and may promote new discourse on the influence of the Mongols in history, it is undermined by numerous mistakes." May recommended against the book's use in history classes,[3] although noting that the book is well written and engaging.[4]
On the other hand, in a 2016 review, Simon Winchester praised "this fine and fascinating book". He appreciated in his review for the New York Times that "Weatherford's writings present us revisionist history on a grand scale, but one as scrupulously well researched (with ample endnotes) as such an intellectual overhaul needs to be".[5] Kirkus Reviews wrote: "Weatherford's lively analysis restores the Mongol's reputation, and it takes wonderful learned detours. ... Well written and full of surprises.”[6]
The book stayed on the New York Times Bestseller List for two weeks in 2004.[7] In a tournament of audiobooks by Audible.com, the book was honored in 2011 as a champion, together with Karl Marlantes' Matterhorn.[8] It was the book of the week by CNN in 2011.[9] On 12 October 2014, the book ranked at 6 on the New York Times e-book bestseller list.[10]
